Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443916, here are decompositions:

  • 3 + 2147443913 = 2147443916
  • 127 + 2147443789 = 2147443916
  • 157 + 2147443759 = 2147443916
  • 283 + 2147443633 = 2147443916
  • 313 + 2147443603 = 2147443916
  • 337 + 2147443579 = 2147443916
  • 349 + 2147443567 = 2147443916
  • 379 + 2147443537 = 2147443916

Showing the first eight; more decompositions exist.
